Hi Folks,
I never found why the draw method in the PlotCanvas class took too long to plot more than 80k points, so I experimented with Matplotlib. At first, I was using the backend Wx, the plotting was damn slow. After using the WxAgg backend in Matplotlib, the plotting turned out to be incredibly fast. I used Numpy to collect the data in the numpy array and it’s indexing function to sort data.
Thank you all for your suggestions.

than matlab.not for plotting with matplotlib, however.
